Numerical control machine tool cutter

The invention relates to the technical field of numerically-controlled machine tool cutters, in particular to a numerically-controlled machine tool cutter which comprises a fixing strip and a cutter body, the rear end of the fixing strip is rotationally connected with a first connecting plate, a mounting groove is formed in the upper side of the front end of the fixing strip, the cutter body is located in the mounting groove, and positioning strips are symmetrically installed on the side walls of the left end and the right end of the cutter body; a bearing plate is movably connected to the side wall of the other end of the fixing strip, and one end of the cutter body makes contact with the upper end of the bearing plate and extends out of the bearing plate. The length of the part, inserted into the moving groove, of the bearing plate can be adjusted when the pin columns are inserted into different insertion holes, so that the length of the part, exposed out of the bearing plate, of the cutter body is adjusted
